"Everything is funnier in retrospect, funnier and prettier and cooler. You can laugh at anything from far enough away.""Funny Aneurysm" Moment is when events, either external or within a series, turn a joke into something disturbing, upsetting, or at the very least really uncomfortable. Harsher in Hindsight is when a tragic and serious event is even worse later. This is the opposite. It's when a later event, such as a current event or something that happened in the series, contrives to make something funnier than it originally was. This is what your literature teacher would call "Life imitating Art". There's a decent list in this College Humor feature and another one in this Cracked.com feature. Note this is not merely something that seemingly predicts something else. For example, black US presidents in fictions are not this trope. A black US president in fiction who has an unfortunate middle name would be. Also note that some examples that might not seem funny to one, might seem funny to another. It depends on attitudes towards Black Comedy and Gallows Humor. Additionally, "hilarious" doesn't just mean "BLAH-HAH-HAH! gut-busting," either. If you go by the word's original definition, it can mean "amusing" or "charming" as well. So any belated lighthearted coincidence would fit under this trope. Almost all examples of Have a Gay Old Time are an example of this trope. Compare Fridge Brilliance, Heartwarming In Hindsight. Contrast "Funny Aneurysm" Moment (when something that was once amusing or awesome is now tinged with tragedy thanks to a Real Life or in-story tragedy), Dude, Not Funny! (when something is considered in bad taste to mock or even mention, no matter what the circumstance), and Harsher in Hindsight (when something dramatic or depressing is now worse due to a Real Life or in-story tragedy).
